The goal of this paper is to generalize some of the existing toolkit of combinatorial algebraic topology in order to study the homology of abstract chain complexes. We defineshellability of chain complexesin a similar way as for cell complexes and introduce the notion ofregularchain complexes. In the case of chain complexes coming from simplicial complexes we recover the classical notions but, in contrast to the topological case, in the abstract setting shellings turn out to be a weaker homological invariant. In particular, we study special chain complexes, which arecones, and a class of regular chain complexes, which we calltotally regular, for which we can obtain complete homological information if an additional condition is fulfilled.
